Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime.
The proposed device, Medical Diode Laser Hair Removal Device (PZ-606VI、PZ-BDT68-01、PZ-BDT68-02、PZ-BDT68-03、PZ-BDT68-04), is a surgical device, which is intended for hair removal, permanent hair reduction on all skin types (Fitzpatrick skin type I-VI);
The device incorporates a diode laser that emits invisible infrared laser radiation centered on a wavelength of 808 nm. According to the selective light absorption theory, the laser can be preferentially absorbed by the melanin in the hair follicle, thus achieving the purpose of permanent hair removal. Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime. Hair growth must remain stable for a certain amount of time and must exceed the entire growth cycle of the hair follicle. Permanent hair removal does not mean that all hair in the treated area is completely lost. Special cooling technology is applied simultaneously during treatment to cool the skin and protect skin.
There are 5 models included, PZ-606VI, PZ-BDT68-01, PZ-BDT68-02, PZ-BDT68-03 and PZ-BDT68-04, the five models have the same intended use, mechanism of action and principle, only the minimum values of energy density and pulse duration are different.

The Fractional CO2 Laser Machine uses a CO2 laser with the emission wavelength of 10600nm to emit focal spots through a high focus lens. The target is water in skin tissue. A certain amount of thermal stripping, more thermal coagulation and obvious thermal effect are produced at the part directly penetrated by the focal spot.
The Fractional CO2 Laser Machine has two operational modes, fractional mode and impulse mode.
- Fractional mode includes three modes: normal, random and midsplit;
- Impulse mode includes three modes: single, continuous and impulse.
The Fractional CO2 Laser Machine has 5 modules: Control display panel module, Main control power module, Light guide arm module, Fan cooling module, Laser module.
The provided FDA 510(k) clearance letter describes a "Fractional CO2 Laser Machine" (K250782) and its substantial equivalence to a predicate device, the "Ilooda Fraxis CO2 Laser" (K172096).
However, the document primarily focuses on demonstrating substantial equivalence through non-clinical performance and safety comparisons rather than detailing specific acceptance criteria for a study that proves the device meets those criteria, particularly in the context of device performance outcomes for intended use. The clearance is based on the device being as safe and effective as its predicate through these comparisons and compliance with relevant standards.
Therefore, many of the requested sections regarding the study that proves acceptance criteria (especially clinical study details, ground truth, expert involvement, and reader studies) cannot be extracted from this document as such studies are explicitly stated to be not included.
Here's an analysis of what can and cannot be extracted:
Acceptance Criteria and Device Performance (Based on Substantial Equivalence and Standards Compliance)
